+ NAME
+ XCreateInsensitivePixmap - create a grayed-out copy of a pixmap
+
+ SYNOPSIS
+ Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
+
+ DESCRIPTION
+ This function creates a grayed-out copy of the argument pixmap, suitable
+ for use as a XmLabel's XmNlabelInsensitivePixmap resource.
+
+ RETURN VALUES
+ The return value is the new Pixmap id or zero on error. Errors include
+ a NULL display argument or an invalid Pixmap argument.
+
+ ERRORS
+ If one of the XLib functions fail, it will produce a X error. The
+ default X error handler prints a diagnostic and calls exit().
+
+ SEE ALSO

+Subject: Patch for Motif ConvertToBitmap
+
+Hi Julian,
+
+I've been working on a wxWin application for image processing. From the
+beginning, I was surprised by the (lack of) speed of ConvertToBitmap,
+till I looked in the source code of image.cpp. I saw that converting a
+wxImage to a bitmap with 8-bit pixels is done with comparing every pixel
+to the 256 colors of the palet. A very time-consuming piece of code!
+
+Because I wanted a faster application, I've made a 'patch' for this. In
+short: every pixel of the image is compared to a sorted list with
+colors. If the color is found in the list, the palette entry is
+returned; if the color is not found, the color palette is searched and
+then the palette entry is returned and the color added to the sorted
+list.
+
+Maybe there is another method for this, namely changing the palette
+itself (if the colors are known, as is the case with tiffs with a
+colormap). I did not look at this, maybe someone else did?
+
+The code of the patch is attached, have a look on it, and maybe you will
+ship it with the next release of wxMotif?
+
